nipple sucking

Nipple stimulation or breast stimulation is stimulation of the breast. Stimulation may be by breastfeeding, sexual activity, or an indirect non-sexual response. As part of sexual activity, the practice may be performed upon, or by, people of any gender or sexual orientation. It may occur with the use of fingers, orally, such as by sucking or licking, as well as by use of an object.
Nipple stimulation may produce sexual excitement, and erect nipples can be an indicator of an individual's sexual arousal. Adult women and men report that breast stimulation may be used to both initiate and enhance sexual arousal, and a few women report experiencing orgasm from nipple stimulation.
